The part of the profiled socket (8) enclosing an insert groove (21) for the heat barrier section is covered together with the inserted heat barrier section (23) by the overhang of the larger pane.

Description

The invention relates to a window or door wing made of at least two glass panes without an outer frame, which in the manner of an insulating glass pane by means of an Ab stand frame are tightly connected and one side the other on all sides protrudes by a protrusion, and with one that runs parallel to the spacer Fitting mounting profile, which is connected to the glass panes, preferably glued, and has a connection surface for fittings.

From WO 98/02 632 such frameless insulating glass window or door leaves with two Glass panes connected to one another via a spacer frame are known, the one pane - preferably the one facing an interior - the other pane - before pulls the outward-facing - overhanging on all sides so that its edge the latter and the edge of a wall-side opening protrudes on all sides. From the interior Here you can see an unframed window and glass surface.

The spacer frame, which is usually provided with an air drying agent, jumps at least against the edge of the larger glass pane, but mostly against back over the edges of both panes of glass so that between its outer ren shell surface and the two parallel circumferential, protruding inside surfaces of the glass panes a groove or groove is formed. There is an admission profile with a groove for receiving and fastening fittings (hinges, bolts and Like.) firmly used as a separate component (screwed, glued). With the well-known Lö solution is at least one leg of the circumferential fitting receiving profile with which smaller glass pane overhanging the inner edge area of the larger glass pane sticks. In one embodiment, the fitting receiving profile further comprises one of the Groove separated cavity, in another embodiment that overlaps with a me Metal reinforcement fitting fitting profile the edge of the smaller glass pane and lies on the outer main surface close to the edge with a sealing lip.

Edge protection for the larger glass pane is not, however, in this construction intended. The load is only transferred via the adhesive joint that is subjected to thrust transfer to the fitting profile. This is all the more important than  With this construction, the larger glass pane is also significantly thicker than the smaller one Disc is.

With a similar known window or door wing (DE 195 09 206 A1) this can Fitting adapter profile in one piece with the spacer frame or as a separate construction be partially trained. In any case, its glued to the inside of the glass panes th leg extended by an angle, which the edges of the glass panes spreads.

DE 29 43 090 A1 discloses a thermal insulation profile on a non-generic insulation lierglas window sash, which is detachably connected with a sash profile and between rule the outer window pane and the frame profile.

Such window or door sashes with spacing and fitting receiving profiles Metal have a good long-term stability, because you have proven adhesive systems disposes. However, the adhesive layer must be protected against embrittlement by ultraviolet protect parts of the incident light. This is achieved in a known manner by means of a applied to the inside of the enamel facing the adhesive. This is z. B. applied by screen printing in a width corresponding to the width of the adhesive layer and then burned in. Other coating processes have ge cannot achieve a shorter lifespan and color stability.

Due to the necessary burning in of the enamel layer, however, the printed glass pane itself toughened (so-called toughened safety glass ESG). The Ver Tempered glass panes can be an advantage on the inside of the wing on the outside, however, is not absolutely necessary. As a side effect Glue is also invisible due to the said enamel layer, so that the visual impression is more appealing than with an uncovered adhesive layer.

In comparison with plastic profiles, the thermal conductivity of the metal profiles, e.g. B. from Aluminum, significantly higher as a spacer or fitting holder. Therefore join Such windows heat loss in the edge area, so that the heat transfer value of the entire window becomes much less favorable than when using art fabric profiles. From DE 93 04 381 U1 a multi-part spacer frame is known, the metallic outer and inner parts with the associated pane sides Contact surfaces are glued. Both frame parts are encircled by insulating bars Plastic interconnected, which is the heat conduction between the two frames prevent ment parts. An assigned outer frame is also corresponding with two  Frame parts and these connecting insulating webs executed, so that overall already good thermal insulation is to be expected. However, this frame construction is relative complex and therefore expensive.

The invention has for its object a window or door at the beginning mentioned type to further develop that the appearance of the frameless The wing is retained, however, the load transfer to the fitting profile and the Thermal insulation effect can be improved.

This object is achieved with the features of claim 1. The features of the subclaims give advantageous developments of this counter pending.

If the fitting profile on its from that with a glass pane inside connected side facing away from the edge of the smaller glass external thermal insulation profile is firmly connected, prevents the latter the direct contact between the glass pane facing the exterior and the wall-proof cut-out frame and thus provides improved thermal insulation for sure. Another direct advantage of this arrangement is that the heat insulation profile also the gap between the fittings filled with an adhesive Recording profile and the glass pane can cover, so that no separate Measures for optical lamination and UV protection of this area must take. The fitting receptacle profile comprises a receptacle, preferably one  Insert groove for releasable insertion of the thermal insulation profile. This is an exchange the thermal insulation profile after a possible damage very simplified.

A particularly tight embedding of the fitting profile in the window or Door leaf and thus a good load transfer of the leaf weight via the adhesive connection on the wing fittings can be reached if the outer surface of the Ab stand frame with the protruding edge areas of the mutually facing On the inside of both glass panes, a gutter that is open to the pane circumference writes in which the fitting mounting profile encompasses adhesive on three sides is.

You can also use the edge lengths of the smaller ones to simplify assembly Glass pane and thus its protrusions from the spacer frame so be measure that an already assembled frame from the fitting professional len just fits over it and glue it onto the protruding edge of the larger outer glass pane can be placed.

In a particularly advantageous embodiment, the part of the loading comprising the receptacle percussion profile and the thermal insulation profile used so dimensioned and appropriate orders that, projected onto the main surface of the window or door leaf, from above the larger glass pane are covered. This will make the outer outline of the Wing determined from the outer edge of the larger glass pane, but you have that in Zen overlap of the larger glass pane over the smaller than Scope with regard to the structural design of the insertion groove, the thermal insulation profiles and the interaction of these components with the wall-fixed cutout frame.

Preferably, the thermal insulation profile includes a baseboard, which is detachable in the receptacle is insertable.

In addition, the thermal insulation profile covers one with appropriate training Edge strip of the surface of the outer glass pane from that of the width of it underlying adhesive layer corresponds. This has the further advantage that you can use this Glass pane no longer has to apply an enamel layer as UV protection and this costs can inexpensively consist of non-tempered uncoated glass.

In a further advantageous embodiment, the thermal insulation profile is under pretension with a lip on the glass pane and has openings for ventilation and drainage  a cavity below the lip.

To improve the thermal insulation effect and to reduce the material are advantageous advanced training in the heat formed from an elastic polymer material Insulation profile formed over the longitudinal course of the hollow chambers.

In a further advantageous embodiment, the bonded web of the Be connects percussion profile when connecting the hardware profile with the The front of the glass pane is angled to cover the edge protection. In order to the outer glass edge is protected against damage; this also shows angle during assembly, a stop for the insertion depth of the individual sections of the fitting profile. Finally, it carries on the bottom edge of the window or Door leaf contributes significantly to the transfer of the load to the frame profile.

The surface of the leg to be glued is another advantageous embodiment provided with spacers for setting a predetermined thickness of the adhesive layer, which are preferably designed as plastic strips or as adhesive tapes based on PU and prevent direct contact of the metal with the glass.

You can further optimize the thermal insulation effect of the window or door leaf, if the fitting profile as a composite of a Me tall rail and an art comprising the insertion groove for the thermal insulation profile fabric profile strand is made. The metal rail and the plastic pro are preferred Filstrang positively connected, but you can also use the two components co-extrude and, if necessary, additionally by means of form-locking elements chern.

Further details and advantages of the object of the invention are evident from the drawing tion of an embodiment and which are discussed below the description.

They show in a simplified representation

Fig. 1 shows a cross section through a first embodiment of the window or door leaf,

Fig. 2 shows a second embodiment in which the fitting-receiving profile to improve its own thermal insulation is a composite profile made of metal and plastic,

Fig. 2a shows a cross section through the modified fitting-receiving profile as the de tail in FIG. 2.

As can be seen from Fig. 1 in detail, the window or door leaf 1 comprises an outer glass pane 2 and an inner, larger glass pane 3 , which extends beyond the outer glass pane 2 on the edge by a few centimeters overhang. With its inner side, ie the side oriented towards the smaller glass pane 2 , when using such wings as a rotating or tilting wing, this forms a stop edge which, when closed, can rest against a wall-fixed frame or cut-out frame. In the case of windows or door leaves opening inwards, the larger glass pane therefore forms the pane of the insulating glass which faces the room, while it forms the outer pane in the case of windows opening outwards. Of course, such sashes could also be used as immovable windows.

The following description is dedicated to an inward opening configuration. The shown section of the edge area of the window or door wing is representative of its entire scope.

The two glass panes 2 and 3 are connected to each other in the manner of an insulating glass pane from a stand frame 4 at a fixed distance. The spacer frame 4 preferably has, as is usual with insulating glass panes, a substantially rectangular cross section. It can be filled in a manner not shown with a dry agent, for example a molecular sieve, and be provided towards the air gap 5 with diffusion openings. It is glued on both sides to the inner surfaces of the glass panes using an adhesive layer 6 (butyl adhesive). Its outer circumferential surface jumps back against the outer edges of both glass panes, so that it forms the bottom of a circumferential, open to the circumference of the glass panes groove or gutter, which can accommodate other components.

At least the glass sheet 3 is provided along the edge of its inside in the usual manner with an opaque enamel layer 7 , which also covers the butyl adhesive layer 6 between the spacer frame 4 and the inside of the glass sheet 3 . It prevents both the inspection of the underlying arrangements and the passage of UV rays, which could damage the adhesive connection in the long term.

Because such all-glass windows or doors do not have a load-bearing frame construction, and the glass panes themselves have to absorb the forces that act on them, the latter are usually prestressed to increase their bending and impact resistance. It may also be sufficient to temper only one of the two panes of glass. This is preferably done in a known manner immediately after the enamel layer 7 has been burned in.

In the already mentioned groove or groove between the spacer frame 4 and the cantilevered edge regions of the glass panes 2 and 3 , a fitting receiving profile 8 made of metal, preferably aluminum, is fixed. It is here before a component separated from the spacer frame 4 , but, as is known, can also be integrally formed with it. It is also basically designed in such a way that one can arrange 9 commercially available, so-called concealed fitting systems in its fitting groove that is open towards the circumference of the glass panes, for example edge gears, cable pulls, turn fittings, turn-tilt fittings, etc.

The fitting receptacle profile 8 also has an elongated leg 10 which extends in a constructional position parallel to the inside of the inner glass pane 3 . It delimits one side of the fitting receiving groove 9 , together with a cantilevered projection 11 which serves as a form-locking element. On the back, the leg 10 is permanently bonded to the latter over its entire height from the spacer frame 4 to the edge of the glass pane 3 . You can use polysulfide glue, but also other suitable glue systems. In order to set the distance and the adhesive layer thickness between the metal of the leg and the glass surface as precisely as possible (a layer thickness of approx. 2 mm is preferred), correspondingly thick parallel double adhesive tape strips 12 on a PU basis are glued on as a spacer along the two ends of the leg. Before assembly, a bead made of the actual PU adhesive 13 is applied to the intermediate surface, which in the installed state is distributed in the space between the leg 10 , the glass pane 3 and the two adhesive tapes. The latter also prevents direct contact between aluminum and glass.

At the free end of the leg 10 , an angled portion 14 projecting outwards over the end face of the glass pane 3 is provided. It lies with the interposition of an elastic strip 15 on the glass edge. This prevents direct contact between the metal / aluminum and the glass edge when the fitting mounting profile 8 is inserted into the said groove or channel after the adhesive layer has been applied. The actual assembly process will be discussed in more detail later.

The bend 14 and the strip 15 also form an edge protection for the end face of the glass pane 3 . In addition to the load transfer function mentioned on the lower edge of the window or door wing, its entire edge, which is sensitive to impacts, is also protected by a front metal edge.

It can also be seen that the side of the leg 10 facing away from the bend 14 forms an abutment surface with which the frameless window or door leaf 1 runs up against the glare or cut-out frame 16 only indicated here and which defines the closed position of the leaf. A thin seal 17 on the cheek surface, which is inserted into a leg formed in the leg 10 with respect to the bend 14 , closes the frame 16 formed between the window or door leaf 1 and the cutout - in the still not shown here Hardware must be installed - against the interior (in the illustration on the right of window or door leaf 1 ).

The bottom of the fitting receiving groove 9 is formed by a bottom wall 18 of the fitting profile 7 , which closes an overlying cavity 19 . The he mentioned, in the fitting receiving groove 8 fitting parts can be on this bottom wall 17 with suitable screws - z. B. Self-drilling screws - are attached.

A leg 9 opposite side wall 20 of the fitting 9 includes a right angle to the bottom wall 18 and the cavity 19 at. It is still covered by the overhang of the larger glass pane 3 , but protrudes beyond the outline of the smaller glass pane 2 . On its rear side, the menut from the side facing away Beschlagaufnah 9 ie, is circumscribed by an approximately C-shaped outline, undercut insertion groove 21 which extends parallel to the fitting location. 9 An elastic, form-fitting hollow baseboard 22 of a thermal insulation profile 23 is detachably fastened therein.

The thermal insulation profile 23 consists of a thermoplastic extrusion product. Numerous hollow chambers 24 extend over its longitudinal course. It is in cross-section substantially L-shaped and angled away over the end face of the outer glass pane 2 so that it can create a lip 25 with slight bias to the main surface of the glass pane 2 at a distance from the end face. It should be expressly noted that the configuration of the positive connection shown here between the insertion groove 21 and the skirting board 22 will also be made more complex and resistant if necessary. The plug or clip connection shown enables light, in any case, the rapid replacement of the thermal insulation profile in the event of any damage or wear. Variations of the position and the angular position of the insertion groove are of course also possible, as long as the free cross section of the loading groove remains unaffected.

It can also be seen in the drawing that the thermal insulation profile 23 in the contact area to the glass pane 2 is easily bordered between the latter and a wall-fixed frame or drip rail 26 . The resulting compressive force must of course not compress the hollow chambers 24 too much, since otherwise the thermal insulation effect of their inner volume would be reduced or even lost. On the other hand, the pretensioning force is sufficient to practically prevent the ingress of water and dirt when the window or door leaf is closed. In any case, openings 27 are also provided in the thermal insulation profile 23 for dewatering and ventilating the free space below the lip 25 .

You become your own preload of the elastic thermal insulation profile - by constructi ve design of the angle between the baseboard and the lip in the relaxed closed stood - so choose that a sufficient security against the ingress of water and dirt is guaranteed even when the window or door leaf is open or should be tilted.

Above the cavity 19 mentioned in the fitting profile, laterally therefrom and above said insertion groove 21 , after inserting the fitting profile 8 into the circumferential groove or groove between the glass panes 2 and 3, there is still a free space which is to be filled as far as possible by an adhesive 28 . The same material is used for this as for gluing the leg 10 to the glass pane 3 . However, while, as discussed, a defined distance and thus a defined adhesive layer thickness is set between the leg 10 and the glass pane 3 so that a reliable introduction of force from the window or door leaf onto the fittings is ensured, such is in the area of the said cavity exact dimensioning not necessary.

So far, the outer glass pane 1 has also had to be provided with a frame-like enamel layer in order to protect the adhesive composition covered by it from light. In the design presented here, however, the enamel layer on the outer glass pane 2 can be omitted because the adhesive 28 is covered by the thermal insulation profile or its lip. Since the glass pane 2 thus does not need a penetration, it can also be manufactured from tempered glass and thus more cheaply.

Within the space covered by the drip rail 26 mentioned, a white elastic sealing strip 29 is arranged fixed to the wall. This rests with a sealing lip 30 against the lower region of the thermal insulation profile 18 which is supported directly on the baseboard 22 . In addition to the seal 12, it forms a further threshold against drafts and heat losses. Between the seal 12 , the cutting frame 16 , the fitting receiving groove 9 , the thermal insulation profile 23 and the sealing lip 30 , a circumferential channel is sealed, which forms a good buffer against heat loss when the window or door leaf is closed.

The embodiment of the window or door leaf shown in Fig. 2 differs from that previously described only in that a modified fitting profile 31 from a composite of a metal rail 32 and a plastic profile strand 33 is used. The outer connection dimensions are unchanged compared to FIG. 1, but the cavity 19 provided there is used to form a form-fitting, insertable connection.

For the sake of clarity, the modified profile is drawn out as a detail in cross section in FIG. 2a. The extension of the leg 10 of the metal rail 32 bil det the bottom 34 of a U-shaped profile section 35th Whose first leg 36 bil det the bottom of the fitting receiving groove and corresponds to the wall 18 of the fitting receiving profile 8th The second leg 37 of the profile section 35 closes the interior space against the adhesive 28 . On the mutually opposite inner sides of both legs 36 , 37 are formed in the longitudinal direction of the metal rail parallel, sawtooth-shaped form-locking elements 38 .

The plastic profile strand 33 can consist of polyamide, polyurethane or PVC and essentially comprises the already known insertion groove 21 for attaching the heat insulating profile 23 . It has a baseboard 39 on its side facing away from it. This also carries longitudinally sawtooth form-locking elements 40 , which are locked with the form-fitting elements 38 of the metal rail corresponding to these.

The slopes of the positive locking elements 38 and 40 are oriented so that the foot bar 39 of the plastic profile strand 33 without excessive force in the inner space of the U-shaped profile section 35 of the metal rail may press 32, but that a release of the latching only with increased effort is possible. A hollow of the baseboard 39 expedient for reasons of extrusion or injection molding supports its elastic deformation when it is inserted and locked.

As shown in FIG. 2 readily, the adhesive layer is applied as thick 28 to enclose the entire material extruded inner region of the positive connection between the metal rail and art upon insertion of the modified fitting-receiving profile 31. The adhesive can also penetrate into the cavity of the baseboard 39 . The surrounding adhesive therefore not only protects the positive connection against separation, but it is also possible to achieve positive locking against pulling out the complete composite fitting receiving profile and thus a particularly high mechanical stability.

By using and the shape of the plastic profile strand 33 , the thermal insulation of the overall arrangement is also considerably improved compared to the embodiment according to FIG. 1, because heat conduction in the metal fitting receiving profile is interrupted in the parting line to the plastic profile strand. The already mentioned screw ben for fastening fittings in the fitting receiving groove 9 can simply be screwed into the baseboard 39 through the first leg 36 . This only selective material weakening has no negative impact on the metal-plastic composite.

In another variant, not shown here, for producing a modified Be percussion profile as a composite of metal rail and plastic profile strand Plastic molded onto the metal rail to form the profile strand (by injection zen, casting). This heat-insulating strand then bridges the main part of the Distance between the two glass panes, so that the thermal insulation of the window or overall door leaf is further improved. Moldable form-locking elements te on the metal rail can have a fe that goes beyond mere adhesion Ensure the most connection between plastic and metal.

It should be noted that both the baseboard 22 of the thermal insulation profile 23 and the baseboard 39 of the plastic profile strand 33 do not necessarily have to be designed as continuous strips, but can also be fully replaced if necessary by their cross-section corresponding individual fastening elements.

In a further variant, the entire fitting mounting profile could be made Manufacture plastic. Compared to such a solution, however, the Verbundkon structure preferred, because you stick to mature systems when gluing metal to glass can operate that are not yet available for gluing plastic to glass.  

Finally, briefly on the manufacture and assembly of a window or door wing to be received.

You cut two glass panes with the required dimensions. At least one of them (glass pane 3 of the figures) is then provided with the enamel layer on the edge and tempered by baking and subsequent rapid cooling. Here you connect the two glass panes by means of the spacer frame, which can also be made entirely of plastic, by gluing. Compliance with the specified distances of the spacer frame from the edge of the two glass panes is ensured by suitable stops of a mounting device.

A round butyl cord is used as the adhesive, which is crushed when the glass panes are placed on top. After tying, the actual window or door wing is ready. The fitting mounting profile has now been prefabricated from several cut sections of one of the design variants described. It can be seen in FIGS. 1 and 2, that one can not simply put on the window or door wing the finished fitting-receiving profile frame, because it has to be immersed at least partially in the sides on the outer circumference umlau Fende groove or channel. The miter-cut individual pieces - one for each side of the window or door leaf - are therefore first loosely added to a frame only by means of corner connectors, so that they are not yet in the frame corners. To insert the corner connector, the cavities provided in the fitting profile are z. B. the cavity 19 in Fig. 1 - used. After the final assembly, the corner connectors remain as stiffening elements in the fitting profile frame.

The plastic or adhesive strips 12 and the adhesive layer 13 are applied to the side of the leg 10 pointing towards the glass pane 3 . The adhesive 28 is introduced into the circumferential groove or groove of the window or door leaf 1 , vorzugwei se applied to the free surface of the spacer frame. The larger glass pane 3 is preferably below. The pre-assembled frame made of fitting profile is placed on top of the overhang. Then one presses its individual sections into the groove until the bend 14, along with the elastic strip 15 lying thereon, bears against the glass edge as a stop for the insertion depth. The bead of adhesive on the leg 10 is distributed as a layer 13 in the space between the adhesive tapes 12 , and the adhesive layer 28 , as shown in FIGS. 1 and 2, partially swells out of the groove or groove laterally / above, reaching below the front side the smaller glass pane 2 arrives. This area is covered later by the thermal insulation profile 23 .

After the adhesive layers 13 and 28 have set, the suitably cut-off sections of the thermal insulation profile 23 are then inserted and the fitting parts are mounted. In a variant of the design shown, the edge lengths of the smaller glass pane 2 and thus their overhangs compared to the Spacer frame 4 are shortened to such an extent that the frame of the fitting profile 8 that has already been assembled is just pushed over and glued to the protruding edge of the larger glass pane 3 can hang up. Between the inner, ie the spacer frame 4 facing outer surface of the frame from loading profile 8 loading and the outer outer surface of the spacer frame 4 , a gap 28 which can be filled with adhesive must remain. The bending around the frame fende bend 14 centers the frame with respect to the larger glass sheet 3 and also sets the said gap exactly.

This embodiment simplifies the assembly process described above, because the loose insertion of the individual fitting receiving profiles 8 with the corner angles and the pushing together of the individual profiles lying on the glass pane 3 and coated with adhesive can be eliminated to form the finished frame.
